Power management not activating consistently/reliably

[Thadude]

Hey,

I've had this problem for a while now and cant seem to pin it down. Basically, my monitors are configured to power off after 10 mins. I like to just walk away from my PC at night and not worry that the monitors are going to stay on all night. However, this fails about 10% of the time and I awake to find my monitors still powered up (2 x Dell 24inch 2407WFP LCD monitors).

What could be causing this? I assume Vista is interpreting something as input which causes the power management to never kick in.

Any ideas?

Thanks for any input !

Is the option Adaptive displat or something similar enabled?

Yes it is! Could this be the problem? I just read up on it and it appears to adjust the timer based on your activity level.. So it shouldn't cause the monitors not to turn off for hours, but lets see! Thanks.
